25 cm to meters is 0.25

1.16+0.25 = 1.41

Answer:

The mean distance to his friends' house is between 2 -3 blocks.

Step-by-step explanation:

1. Mean = Average.

Average = (n1+n2+n3....nx)/x

2. The average = 1+2+5+3+2+2+5+3/8

3. Therefore, the answer is 2.875, making the mean between 2 and 3

Answer:

The statement that supports the data is the mean distance to his friends' houses is in between 2 and 3 blocks.

Step-by-step explanation:

What is mean, median and mode?

Mean: The average of the given data points.

Median: The central point of the whole data set.

Mode: The number that occurs for the maximum times in the data set.

Given:

Karl records the number of city blocks from his house to each of his friends houses.

Data set for the number of city blocks to eight friends houses:

{1, 2, 5, 3, 2, 2, 5, 3}

The first option: it is given that the maximum number of blocks the Karl lives from his friend is 4, but according to the data set, the maximum number of house blocks should be 5.

Hence, this option is incorrect.

The second option: It is given that the mode shows that Karl has 3 friends who live 3 blocks from him, but according to the given data set Karl has 3 friends who lives 2 blocks from him. Hence the mode is 2.

Hence, this option is incorrect.

The third option: It is given that the minimum distance from Karl's house to a friend's is 2 blocks, but according to the given data set the minimum distance from Karl's house to a friend's is 1 block.

Hence, this option is incorrect.

The fourth option:  It is given that the mean distance to his friend's houses is in between 2 and 3 blocks.

We will find the mean for the given data set.

⇒ Mean = (Sum of all the data points) / (Total number of data points)

⇒ Mean = (1 + 2 + 5 + 3 + 2 + 2 + 5 + 3)/8

⇒ Mean = 23/8

⇒ Mean = 2.875

∴ The mean distance from Karl to his friend's houses is 2.875 which is in between 2 and 3.

Hence, this option is correct.

Therefore, the fourth option which says the mean distance between Karl and his friend's houses is in between 2 and 3 is correct.

The 95% confidence interval for the population mean is (47.00, 48.90).

A sample of size n=78 is drawn from a normal population with a standard deviation of σ=5.1. The sample mean is x=47.95.

Using this information, we can estimate the population mean using the formula:

μ = x ± z*(σ/√n)

where μ is the population mean, x is the sample mean, z is the z-score for the desired level of confidence (e.g., 1.96 for a 95% confidence interval), σ is the population standard deviation, and n is the sample size.

Assuming a 95% confidence level, the z-score is 1.96. Plugging in the given values, we get:

μ = 47.95 ± 1.96*(5.1/√78)

Solving for the upper and lower bounds of the confidence interval, we get:

μ = 47.95 ± 0.95

So the 95% confidence interval for the population mean is (47.00, 48.90). This means that if we were to repeat this sampling process many times, we would expect the true population mean to fall within this interval 95% of the time.

Answer:

Let B be the number of balls Brandon had initially, and C be the number of balls Cody had initially.

We know that Brandon had 40% more balls than Cody, so:

B = 1.4C

We also know that Brandon gave 30% of his balls to Cody, so Cody received:

0.3B

And we know that Cody gave 50% of his balls to Brandon, so Brandon received:

0.5(0.3B) = 0.15B

Now, we can set up an equation to represent the final number of balls Cody had:

C + 0.3B - 0.5(0.3B) = C - 0.15B

And we know from the problem that Cody had 852 less balls than Brandon in the end, so:

C - 0.15B = B - 852

We can substitute B = 1.4C into this equation to get:

C - 0.15(1.4C) = 1.4C - 852

Simplifying this equation, we get:

0.79C = 852

Solving for C, we get:

C = 1078

And since B = 1.4C, we have:

B = 1.4(1078) = 1511.2

So Brandon initially had 1511 balls. However, since we're dealing with whole numbers of balls, we need to round to the nearest integer. Therefore, the final answer is:

Brandon initially had 1511 balls

The total purchase is  $18.90.

We have,

A discount would reduce the cost of the purchase. A tax increases the cost of the purchase.

The first step is to determine the total cost of the items purchased.

Total cost = (cost of lb of cheese x lb bought) + (cost of sliced ham x lbs bought) + (cost of bread x loaves bought) + (cost of a bag of potato chips x number of bags bought) + (cost of one salsa container x number of containers bought)

(1.99 x 1/2) + (3 x 3.29) + (1.59 x 2) + (2 x $3) + (1.39 x 1) = $20.39

Since, the total cost is greater than $20 she qualifies for the 10% discount

Total cost after the discount = (1 - 0.1) x $20.39

0.9 x $20.39= $18.35

Cost after the tax = (1 + 0.03) x $18.35

x⁴ - 8x² + 17 is the function that represents the fog(x).

To find fog(x), we first need to find g(f(x)), which means we need to substitute the expression for f(x) into the expression for g(x):

g(f(x)) = g(x² - 4)

Now, we can substitute the expression for g(x) into the above expression:

g(f(x)) = (x² - 4)² + 1

The 90% confidence interval for the mean body temperature of adults in the town is approximately (97.299, 98.529).

The given data points are:

97.1, 98.1, 98, 97.7, 97.4, 99.3, 96.8

Step 1: Calculate the sample mean (µ):

µ = (97.1 + 98.1 + 98 + 97.7 + 97.4 + 99.3 + 96.8) / 7 ≈ 97.914

sample standard deviation (s):

≈ 0.839

Step 3: Calculate the standard error (SE):

SE = s / sqrt(n)

≈ 0.839 / sqrt(7) ≈ 0.317

Step 4: Find the t-value for a 90% confidence interval with 6 degrees of freedom (n - 1 = 7 - 1 = 6).

Using a t-distribution table  we find that the t-value is approximately 1.943.

Step 5: Calculate the margin of error (ME):

ME = t-value * SE

≈ 1.943 * 0.317 ≈ 0.615

Step 6: Calculate the confidence interval:

Lower limit = µ - ME ≈ 97.914 - 0.615 ≈ 97.299

Upper limit = µ + ME ≈ 97.914 + 0.615 ≈ 98.529

So, the 90% confidence interval for the mean body temperature of adults in the town is approximately (97.299, 98.529).

The production cost for one lollipop is 5 dollars.

Let's assume the production cost for one lollipop is x dollars.

If Lewis sells one lollipop for 5 dollars, his profit = 5 - x dollars.

If Lewis sells three lollipops for 10 dollars,

Each lollipop would cost = 10/3 dollars ≈ 3.33 dollars.

So, if he sells three lollipops, his revenue would be 3 × 5 = 15 dollars, and his total cost would be 3 × x dollars = 3x dollars.

Therefore, his profit would be 15 - 3x dollars.

Since Lewis' profit is the same whether he sells one lollipop or three lollipops, we can set the two profit equations equal to each other and solve for x:

5 - x = 15 - 3x

2x = 10

x = 5

Therefore, the production cost for one lollipop is 5 dollars.

3. We deduce that a reasonable domain for this quadratic function is t ≥ 0 or {0, ∞}.

4. The intravenous drug must be administered to the patient between the time interval 1.25 ≤ t ≤ 20.

To get this, we will determine time when the concentration would be 0.5 mg/L. We will substitute value of the concentration and then solve the quadratic function for time (t):

c(t) = 20t/(t² + 4)

0.5 = 20t/(t² + 4)

0.5(t² + 4) = 20t

0.5t² + 2 = 20t

0.5t² + 2 - 20t = 0

t² + 4 - 40t = 0

t² - 40t + 4 = 0

Time t = 38.8998 ≈ 40 hours.

Answer:

Step-by-step explanation:

The 40 degree angle we are given is called an angle of depression. Because of geometry and the fact that the base of the triangle and this dotted line are parallel to one another, the base angle inside the triangle is also 40. These are called alternate interior angles. The x represents the hypotenuse of the triangle. We can use right triangle trig to find it. The side measuring 500 is OPPOSITE the reference angle of 40 and the missing side is the HYPOTENUSE, so the trig ratio we will use is sin which is, according to SohCahToa, opposite side over hypotenuse; namely:

[tex]sin40=\frac{500}{x}[/tex]

The probability that Jess will win only the third game out of three games is 0.144, or 14.4%

To calculate the probability that Jess will win only the third game out of three games, we will use the concept of independent events. In this scenario, we have the following events:

1. Jess loses the first game.
2. Jess loses the second game.
3. Jess wins the third game.

Since the events are independent, we can calculate the probability of this specific sequence occurring by multiplying the probabilities of each individual event:

1. Probability of losing the first game: 1 - 0.4 = 0.6
2. Probability of losing the second game: 1 - 0.4 = 0.6
3. Probability of winning the third game: 0.4

Now, we multiply these probabilities together:

0.6 * 0.6 * 0.4 = 0.144

So, the probability that Jess will win only the third game out of three games is approximately 0.144, or 14.4% when rounded to three decimal places.

We have,

To find the place value of the number in the thousand's place for the number obtained by adding 60 tens, 58 hundreds, and 685 ones, we can start by realizing that 60 tens are the same as 600, and 58 hundreds are the same as 5800.

Therefore, we have:

600 + 5800 + 685 = 7085

So the number is 7085.

The digit in the thousand's place is 0 since there is no digit in the thousand's place.

Therefore, the place value of the number in the thousand's place is 0.

To determine if the number is even or odd, we can look at the unit digit, which is 5.

Since 5 is an odd number,

The entire number is odd.

2.

The predecessor of a number is the number that comes before it, and the successor of a number is the number that comes after it.

For example,

Let's say we want to find the predecessor and successor of the number 7.

The predecessor of 7 is 6, since 7 - 1 = 6.

The successor of 7 is 8, since 7 + 1 = 8.

c) the comprehensive income for Bonita Company is $173,310.

d) Since, we are not given the beginning balance of retained earnings, we cannot calculate the exact retained earnings balance at December 31, 2025.

Given that;

Presented below is information related to Bonita Company at December 31, 2025, the end of its first year of operations.

Sales revenue : 335,550

Cost of goods sold : 135,580

Selling and administrative expenses : 54,900

Gain on sale of plant assets: 30,790

Unrealized gain on available-for-sale debt investments: 9,880

Interest expense: 6,050

Loss on discontinued operations: 12,200

Dividends declared and paid: 5,060

(a) The cost of items sold, selling, and administrative expenses must be subtracted from the revenue from sales in order to determine the income from operations.

Revenue from operations is equal to sales revenue minus the cost of the goods sold plus selling and administrative costs.

Operations profit = $335,550 - $135,580 - $54,900 $145,070

was earned through operations.

As a result, Bonita Company's income from operations is $145,070.

(b) We must add or deduct all gains, losses, and expenses from the income from operations in order to determine the net income.

Net income is calculated as follows:

Income from operations - Loss on ceased operations - Gain on sale of plant assets - Unrealized gain on debt investments that are available for sale Net income equal

$145,070 + $30,790 + $9,880 + $6,050 + $12,200 - $5,060.

$163,430 in profit

As a result, Bonita Company's net income is $163,430.

(c) To determine the comprehensive income, we need to add or subtract all gains, losses, and expenses that are not included in net income. In this case, the only item that needs to be added is the unrealized gain on available-for-sale debt investments.

Comprehensive income = Net income + Unrealized gain on available-for-sale debt investments Comprehensive income

= $163,430 + $9,880

Comprehensive income = $173,310

Therefore, the comprehensive income for Bonita Company is $173,310.

(d) To calculate the retained earnings balance, we need to start with the beginning balance of retained earnings (which is not given in this problem) and add the net income, then subtract any dividends declared and paid.

Retained earnings balance = Beginning balance of retained earnings + Net income - Dividends declared and paid Retained earnings balance

= Beginning balance of retained earnings + $163,430 - $5,060

Retained earnings balance = Beginning balance of retained earnings + $158,370

Since, we are not given the beginning balance of retained earnings, we cannot calculate the exact retained earnings balance at December 31, 2025.
